This listing is for ONE Choke Tube. Here are factory choke tubes for the tried and true standard Rem-Choke system in Remington 12 gauge shotguns. Manufacturer was Remington Arms of Ilion, NY, and its subcontractors. We estimate these were manufactured in 2012 or 2013. Construction is Stainless Steel. Muzzle Diameter is .689, Full Choke for Lead Shot only; and So marked. Recent production tubes marked Full Steel or Lead do not have as tight muzzle diameter as these older ones. This tube is somewhere in the vicinity of an Extra Full, but recent standards. It was Not designed for steel shot or rifled slugs. Finish is brushed surface stainless. This tube will Not fit any Remington shotgun marked ProBore. It will only fit standard Rem-Choke threaded, 12 gauge Remington shotguns, and a few Turkish made shotguns that were threaded for Rem-Chokes. These tubes are all new and unfired, repackaged from ca. 2012 factory bulk shipment to a now defunct South Carolina distributor. Replacement pricing on extra fulls with this type constriction is upwards of $40 apiece. We’re offering them, however, at a discount due to the distributor liquidation they came from.
